400W YAG Laser Welding Machine for LED Letters Logo Ads with Dual Path
Channel Letters Laser Welding Introduction
With the booming of global advertising industry, metal letters has been more and more popular because of its colorfulness, attractiveness, heating-proof, frozen-proof, no deformation, no fadedness (8-10 years color preservation), corrosion proof, rain-proof, and spontaneous combustion proof and some other good features. AD metal letters are made of stainless steel, aluminum, copper or other metal sheet being cut, polished, hemmed, and welded. The core feature of AD metal letters is being rustproof, with long life span and dimensional looks. It’s widely used in LED illuminated billboard, exterior/interior signs, branding, door plate and etc.
Regular combination and fixing of metal letters are done via glue, rivets or soldering, but all of them have big defects. Metal letters combined by glue always get loose with time goes by, especially at outdoors. Fixing by rivets sounds good, but not good-looking. Soldering is never a green way of fixing metal letters because of the poisoning gas produced when processing.
However, laser welding technology makes two metal sheets become one only by a few melting spots. From any aspect, laser welding is the best solution and the greenest.
Channel Letters Laser Welding Features
1. Red light spot fast positioning, CCD display, microscope optional
2. High working speed: 6 times faster then traditional TIG or MIG welding
3. Slight distortion and less heating affect
4. Capable of partial heating process
5. Able to deal with complex, profiled, or tiny letters
6. Low noise and no pollution
7. Ultrafine positioning rod makes corner welding easier without changing position
8. Laser cavity can move in all directions manually in order to weld letters of different size and in different shape
9. Parameter setting is very easy; up to 10 sets of parameters can be memorized for different application.
